[0005] In order to improve the safety of workers, the present application provides a drying box with high safety.

[0006] The present application provides a drying box with high safety, which adopts the following technical solution:

[0007] A drying box with high safety comprises an oven, a box door, a storage trolley for storing objects to be dried, and a linkage part, wherein the box door is rotatably connected to the oven, the storage trolley is slidably connected in the oven along a direction of entering and exiting the oven, the linkage part comprises a linkage gear and a linkage rack, the box door is used to drive the linkage gear to rotate, the length of the linkage rack is parallel to the moving direction of the storage trolley, the linkage rack is arranged on the storage trolley, and the linkage rack is meshed with the linkage gear.

[0008] By adopting the above technical solution, the holding trolley is used to hold the materials to be dried. When the holding trolley needs to be sent into the oven, the staff can turn the oven door. The rotation of the oven door drives the linkage gear to rotate. The rotation of the linkage gear drives the linkage rack to move. The linkage rack drives the holding trolley to enter the oven. The oven dehydrates and dries the materials to be dried in the holding trolley. After the materials are processed, the staff opens the oven door and turns the oven door. When the oven door rotates, it drives the linkage gear to rotate. The linkage gear engages with the linkage rack. The linkage rack drives the holding box to move away from the oven. There is no need for the staff to reach into the oven to take out the holding box, thereby improving the safety of the staff.

[0009] Optionally, a sliding track is provided in the oven, and the length direction of the sliding track is parallel to the sliding direction of the storage trolley. The storage trolley includes a base plate and a plurality of storage boxes. The base plate is slidably connected to the sliding track, and a snap-in groove is provided on the upper end surface of the base plate. A snap-in block that is snap-fitted with the snap-in groove is provided on the lower end surface of the storage box, and a mating groove that is snap-fitted with the snap-in block is provided on the upper end surface of the storage box.

[0010] By adopting the above technical solution, the sliding track ensures that the linkage rack is in meshing state with the linkage gear during the movement of the base plate. The storage box cooperates with the clamping groove through the clamping block, thereby reducing the relative slippage of the storage box and the base plate during the movement of the base plate. The stacking of several storage boxes is achieved through the cooperation of the matching groove and the clamping block, which can improve the drying and dehydration efficiency of the materials to be dried.

[0011] Optionally, a blocking block is provided on the sliding track, and the blocking block is used to limit the linkage gear from disengaging from the linkage rack.

[0012] By adopting the above technical solution, the blocking block limits the bottom plate from disengaging from the sliding track, reduces the occurrence of the linkage gear and the linkage rack disengaging, ensures that when the oven door is closed, the storage box is located in the oven, and improves the rationality of the oven structure.

[0013] Optionally, the oven is provided with a seal for sealing the oven door, the seal includes a sealing screw and a sealing handle, the sealing screw is horizontally arranged, one end of the sealing screw is rotatably connected to the side wall of the oven along a vertical direction, the sealing handle is threadedly connected to the sealing screw, and the sealing handle is used to abut the end surface of the oven door facing away from the oven.

[0014] By adopting the above technical solution, when the oven is drying and dehydrating the material to be dried, in order to reduce the loss of heat inside the oven, the sealing component can reduce the heat escaping from between the oven and the oven door. When the oven door is closed, the staff can rotate the sealing screw so that the sealing handle is located on the side of the oven door away from the oven. Thereafter, the sealing handle is rotated relative to the sealing screw until the sealing handle abuts against the oven door, and the oven door is sealed with the oven, which greatly improves the utilization rate of heat and the drying efficiency of the oven.

[0015] Optionally, the oven is provided with an exhaust assembly for reducing hot air from rushing out of the oven, the exhaust assembly includes an exhaust pipe and an exhaust fan, an exhaust hole is opened on the side wall of the oven, the exhaust pipe is connected to the exhaust hole, and the exhaust fan is arranged in the exhaust hole.

[0016] By adopting the above technical solution, when the material is dried, heat will escape from the door when the door is opened, which may cause danger to the staff. Therefore, the staff can start the exhaust fan, which will discharge the heat from the oven into the exhaust pipe, reducing the occurrence of heat directly rushing to the staff.

[0017] Optionally, a blocking member for blocking the exhaust hole is provided in the oven, and the blocking member includes a blocking plate, and the blocking plate is slidably connected to the inner wall of the oven.

[0018] By adopting the above technical solution, when the oven is heated, it is necessary to ensure that heat does not escape from the exhaust pipe. The staff can first slide the sealing plate to seal the exhaust hole. The sealing piece has a simple structure and is easy for the staff to operate.

[0019] Optionally, the blocking member also includes a blocking spring and a push rod, the blocking plate is slidably connected to the inner wall of the oven along the moving direction of the container trolley, the length direction of the push rod is parallel to the sliding direction of the blocking plate, one end of the push rod is arranged on the blocking plate, the blocking spring is used to move the blocking plate away from the exhaust hole, and the push rod is used to abut against the end face of the oven door facing the oven.

[0020] By adopting the above technical scheme, when the oven door is opened, the oven door gradually moves away from the oven, and the push rod is always in contact with the oven door under the action of the blocking spring. At this time, the blocking plate slides, and the exhaust hole cannot be blocked by the blocking plate. The heat is discharged into the exhaust pipe by the exhaust fan. As the opening angle of the oven door gradually increases, the exhaust hole is completely exposed. At this time, the push rod is separated from the oven door, and the elastic potential energy of the blocking spring is released; when the oven door is closed, the oven door will abut against the push rod, and the push rod will drive the blocking plate to move. The blocking plate will compress the blocking spring. The blocking spring has elastic potential energy. When the oven door abuts against the oven, the blocking plate completely blocks the exhaust hole. The blocking member reduces the escape of heat during the operation of the oven, and gradually opens the exhaust hole during the opening of the oven door, thereby reducing the damage of heat to the staff.

[0021] Optionally, the storage box is provided with a handle for the staff to hold conveniently.

[0022] By adopting the above technical solution, the handle makes it easier for the staff to transfer the container, thereby improving the rationality of the equipment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The linkage realizes the linkage between the opening of the oven door and the sliding movement of the food trolley, which reduces the need for workers to put their hands into the oven and improves the safety of workers;

[0025] 2. The seal improves the sealing effect between the oven and the oven door;

[0026] 3. The exhaust assembly is used to reduce the heat rushing to the staff when the door is opened. BRIEF DESCRIPTION OF THE DRAWINGS
